Summary Challenges 2 1 South Platte Overview South Platte Basin Overview Diverse Needs

Municipal Industrial Agricultural Environmental Recreational 4 Municipal and Industrial Water Needs The east slope is home to 80% of the States population (the Metro and South Platte Basin account for about 70%) Large industries include energy production, manufacturing, brewing, and food processing

Power generation at coal and natural gas fired facilities 5 Municipal & Industrial (M&I) Water Supply Gap in the South Platte Basin 2050 Gap Existing Supply *Based on SWSI 2010 Medium Water Demands 6 Agricultural Water Needs

1.4 million acres of irrigated land Seven of top ten agricultural producing counties in the State Represents approximately 75% of agricultural sales statewide Processing of West Slope agricultural products 7 Agricultural Water Shortages (2050) Gap 262,000 AFY Gap 160,000 AFY *Based on SWSI 2010 Agricultural Needs Projections 8

Environmental and Recreational Enjoyment of environmental and recreational values South Platte Basin is a gateway to tourism throughout the State o South Platte Basin is home to the most visited State Parks o Environment and recreational opportunities important to quality of life o Various Attributes of Importance within the Basin State endangered, threatened, or species of special concern o Important Riparian Habitat o Migratory Bird Viewing/Hunting

o Fishing (including Gold Medal fisheries) o Recreation (including skiing and whitewater and flatwater boating ) o 9 2 Overarching Themes & Goals Overarching Themes for South Platte BIP A Good Colorado Plan Needs a Good South Platte Plan

Solutions must be pragmatic, balanced, and consistent with Colorado law and property rights The South Platte River Basin will continue its leadership role in efficient use and management of water A balanced program is needed to investigate, preserve, and develop Colorado River options 11 Eight Goals and Measureable Outcomes 1. 2.

3. 4. 5. 6. 7. 8. Agriculture Municipal Water Conservation, Reuse and Efficiency Identified Projects and Processes South Platte Storage and Other Infrastructure Water Quality New Colorado River Supply Environmental and Recreational Statewide - Long-term 12

3 The South Platte Vision The South Platte Vision Meeting the Municipal Supply Gap Successful IPPs Conservation and reuse Multipurpose projects Storage, additional conveyance and system integration Environmental and recreational protections and enhancements Agricultural transfer through ATMs where feasible New Colorado River supply

14 The South Platte Vision Future Agricultural Production Minimize the impacts of traditional dry-up Encourage continued agricultural production and restoration of curtailed production Integrated development of new Colorado River Supply 15

The South Platte Vision Protecting Environmental and Recreational Attributes Identify and implement attribute-specific projects to enhance environmental and recreational attributes Encourage cooperative projects to enhance environmental and recreational attributes Encourage funding and cooperation

Promote cooperative storage for environmental and recreational needs The South Platte Vision Collaborative Statewide Approach The Roundtables envision that if state water project(s) are considered they would: o Supply water to communities with enhanced levels of conservation & reuse o Provide environmental and recreational enhancements for both east and west slopes

17 4 Challenges 16 Major Challenges in Meeting the Gaps 19 16 Major Challenges in Meeting the Gaps 9. Republican River Basin water use constraints 10.

Programs to manage and recover protected species and their habitats 11. Water quality management 12. Time and cost for regulatory decisions on new water projects 13. Diverse environmental and recreational water needs and concerns 14. Vulnerability to water service disruptions

15. Opportunities for further system interconnections 16. Roles of elected officials, business community and the general public in water supply planning 20 The Challenges Drive the Solutions South Platte BIP

Variable 17,500 7,225 South Platte River Basin will continue its Leadership Role in Efficient Use and Management of Water 27 3. Maximize effective use of South Platte Supplies 28 4. Minimize traditional agricultural buy and dry use ATMs where practical Historically, traditional agricultural transfers (buy and dry) between willing buyers and sellers to meet M&I demands

Alternative Transfer Methods (ATMs) o o o o o Minimize impact on local economy Minimize societal impacts Minimize environmental and recreational impacts Provide funding sources for agricultural users Optimize both agricultural and nonagricultural benefits

Pilot projects underway through CWCBs ATM Grant Program While promising, there are numerous technical, legal, institutional and financial issues that need to be addressed 29 5.

do not support the default agricultural transfer only plan Seek to develop balanced, integrated plan including Colorado River projects and agricultural transfers for the overall benefit of Colorado A Balanced Program is needed to Plan and Preserve Colorado River Options 37 7. Manage risk of climate change impacts Resilient water storage and conveyance infrastructure

Use of safety factors Evaluate potential system vulnerabilities Collaborative, regional approaches (such as WISE) 38 8. Facilitate effective South Platte communication and outreach programs Suggested Activities: Develop consistent message to describe water supply gaps

Leverage communication professionals Complement existing state efforts Develop and maintain basin-specific tools and approaches Establish success metrics 39 9.
